' This invention relates to water closet combinationsof the siphon jet type, and has for itsy object to improve the jet structure of my former Patent No. 1,362,062, dated Decem- 5 ber 14, 1920, whereby the stream of the flushingv water is delivered from one side of the *up-leg, at a considerable distance above, in'

stead of directly from the bottom of the well, which together with the up-leg forms the ywater ,seal or trap of the bowl. positioning the jet opening, the distance the water must flow. to reach the crest of the dam is materially shortened, which tends to greatly quicken the siphon action of the closet. But its greatest value lies in the elimination of the old jet structure, which according to my former patent, followed the usual practice of forming the jet opening in the bottom of the well of the bowl, and then molding upon the under surface of said bottom a hollow clay part that communicates by a lateral with the usual by-passage that supplies water to the jet. This old structure has always been -a source of more or less trouble, due to shrinkage checking or cracking, either during the kiln firing, or by the action of frost in winter, and caused leakage i and discarding of the bowl. In the present case, the jet nozzle is disposed wholly within an external passage located at4 one side of the bowl proper, discharges through the adjacentwall of the up-leg, .which facilitates the directing of a powerful jet in a diagonal course across said leg to create the zig-zag discharge referredl to in the former patent.

The various features and parts of the in- Vention Will be'understood from the detailed description which follows, and by reference to the accompanying drawing, in which- Figure 1 is a side elevation of a closet bowl, showingthe external hollow rib. i Fig. 2 is a broken side elevation showing the rib in section, also showing in .section the jet passage Within the rib. Fig. 3 is a central vertical longitudinal section, taken on line 3 3 of Fig. 4, showing the jet opening located in. the up-leg of the discharge passage. Fig. 4 is a vertical cross-sect on taken on line 4 4 of Fig. 3. And Fig. 5 is a broken top plan view of the bowls of Figs. 1 and 3, show- By thus `Figs. 3, 4iand 5).

REISSUED In the drawing, the bowl 2 substantlally 55 l conforms to the showing of my former patent, and comprises what is known as a reverse-type siphon jet closet bowl, 2 is the usual flushing rim, which receives the water from an inlet chamber 3, the latter in turn so receiving the water from a rearwardly extending' hollow lip 4, which is disposed Within a similarly projecting housing 5. The lip 4 is formed with an upwardly facing opening 4 to which the usual offset or 65 spud connections leading from the flush tank (not shown) may be applied and hidden by the housing. 2 represents the up-leg of the Siphon structure, by which the bowl 1s vemptied. 2b is the down-leg of said structure, 70 which communicates with the up-leg.A at the crest of 'the usual dam 6, to form a continuous passage for the contents of the bowl to the soil-pipe via a bottom opening 2's (see One lateral wall 2d, of the 75 discharge passage, is preferably disposed in a vertical plane, as best seen in Fig. 4while the opposing wall 2" bulges outwardly,as shown at 2t in Figs. 4 and 5, for deflecting a portion ofl the up-flowing discharge to-,gg wards the said point by the force of the jet, as explained.l After'the said diverted portion of the discharge from the bowl gravitates from the dam, it encounters an ,opposing bulge 2X, which causes the stream to shoot, g5 in the form of a sheet, across the bore of the down-leg and impin'gc the opposite wall 2d,

as indicated by the oblique dotted line a in Fig. 4. This divides the down-leg momen` tarily into two chambers :tj and the cham- 90 ber.m"containing any air that may be pres-` .ent in the down-leg when the Siphon action I finally forced downwardly into the soil-pipe.

The portion of the flushing water that supplies the jet in the present case, gravitates .from the inlet chamber 3', or more particularly from an opening 4a of the hollow lip 4, by means of an oblique hollow rib 7 that is `imposed or molded upon the external surface of the wall 2d, as shown in the several views. The rib 7 extends from the port 4a to about the plane of the bottom of the well p, and within said rib is formed a smaller hollow rib 8, the latter having a normally open lower end 8', and its upper end terminating at an opening 9,1 which is formed in the adjacent wall 2d of the up-leg (see Figs. 2, 3 and 5). 'The rib 8 is prefera. bly disposed at an angle relatively to the f longitudinal axis of the rib 7 in order to dis rect the jet diagonally across the `up-leg towards the point 2f, as explained. By disposing;` the receiving end 8 of the jet rib near thefbottom end of the passage 7, the discharge from rib 8 is effected by substantially the full force of the flushing head, and the jet openin 9,-being disposed in a higher than normal plne, as compared with the older style jet o enings of the well, the jet is able to start the' siphon action practically instantly. This,

when taken with the means for entrapping and disposing of the atmospheric pressure 1n the down-leg, as explained, greatly accelerates the emptying of the bowl, which is very desirable. The added feature of the housing 5 and the lip 4 of the present case, is merely for the purpose of showing the adaptability of my novel and sim le jet structure to the old, as well as, to tliedatest improvedv standard siphon jet closet bowls.

Having thus described my invention, what I claim, 1s-

.1. A siphon jet water 'closet bowl having a flushing rim and up and down legs to discharge the contents ofthe bowl, a hollow rib molded to a lateral wall common to said legs,

said wall having a jet opening within the upleg above the plane of the well of the bowl, anda rib of smaller caliber disposed within the larger rib adapted to discharge the water received from the larger rib through said opening and towards the top of the uplegto initiate the siphon action ofthe bowl.

2. A water closet bowl including a flushing rim, up and down legsv for discharging the contents of the Bowl, a hollow rib molded to a lateral wall common to said legs, an inlet chamber communicating with the rim and said hollow rib, said wall having a jet opening within the up-leg, and a smaller hollow rib molded to said wall within thelarger rib adapted to discharge the contents of the larger rib through said opening at an angle to the axis of the larger rib and said up-leg. v

3. A siphon jet water closet bowl including afflushingrim, an inlet chamber, and up Vandfdown vlegs for emptying the bowl, one

wall common to said legs being perforated between the ends of the up-leg, a hollow rib molded to said wall communicating with said chamber adapted to conduct a portion of the ter rib adapted to discharge a jet throughA said ripening towards the top of the u1u-leg.`

siphon jet water closet bowl having l in combination with the flushing rim, a iushing inlet communicating with the rim and up and down legs for the venting of the bowl, and having one wall common to said legs disposed in a vertical plane, of ,a hollow rib molded to said vertical wall, said rib com,- municating with said inlet and extending obliquelyl substantiallyvto the plane vof the well of the bowl, and a smaller hollow rib molded within the larger rib and disposed at an angle to the longitudinal axis of the larger rib adapted to discharge a jet of water through an opening located within'the upleg in a diagonal coursevacross the up-leg to start the siphon action of the bowl;

- In testimony whereof I aiiix my signature.
